概要 Nonequilibrium molecular dynamics simulations are performed for force-driven argon gas nanochannel flow to investigate the effect of the nanoscopic wall structure on the gas flow characteristics. A face-centered cubic wall structure is first investigated. It is confirmed that the fcc (111) surface structure induces the fastest flow, followed by the fcc (100) and (110) surface structures Unlike liquid flow in a nanochannel, the density of the monolayer adsorbed on the wall surface greatly depends on the wall configuration. A lattice wall configuration that allows stronger adsorption of molecules induces higher velocity flow. From simulations with different wall molecule bond lengths, the gas flow is affected more by the surface roughness than adsorption of gas molecules to the wall.
